Kuwait's lower court on Monday acquitted 70 opposition activists including nine former MPs of charges of storming the parliament building in the oil-rich Gulf state two years ago.

"All the defendants were found not guilty" of charges of storming a public building, assaulting police, resisting orders and damaging public property, in the ruling by judge Hisham Abdullah.

Hundreds of opposition activists entered the seaside building in Kuwait City after a noisy November 16, 2011 protest to demand the removal of then-prime minister Sheikh Nasser Mohammad al-Ahmad Al-Sabah, over corruption allegations.

Sheikh Nasser resigned two weeks later and a new government was formed, after which the emir, Sheikh Sabah al-Ahmad Al-Sabah, dissolved parliament and called fresh polls.
